Most hated Zelda game final/end battle.

I'm sure everyone (who has played a Zelda game) has at least 1 final or end (whatever you wanna call it) battle that they hate.

For me, the most hated end battle is definitely the final battle of Spirit Tracks.

The 2nd (I think) phase where you have to protect Zelda as she charges up is definitely a pain in the ass. The part that really pisses me off the most would be how every time Zelda got hit by 1 of Malladus' fireballs, she had to start the charging process all over again.

Let's not forget the duet part which for me was really a pain in the ass (today at least). I said that whoever thought up the idea of implementing the musical duets sequences into the game needs a nice swift kick in the ass.

Of course with all these constant setbacks, I could become very angry and start cussing like a sailor.

Because of those 2 reasons, a boss battle that should only take me roughly 15-20 minutes takes me 40 minutes to 1 hour to complete.

Those are the reasons as to why I rank the final/end battle of Spirit Tracks my most hated final battle in Zelda history.

What end/final boss battle from a Zelda game do you hate the most?
